TOBACCO-MOLD.

SPECIFICATION forming part of Letters Patent No. 301,585, dated July 8, 1884.

Application med December 1'1, 18H3. (N model.)

To all whom, it meaty concern: v

Beit known that I, Janes M. Gistron, ot' Louisville, in the county of Jefferson and 'State of Kentucky, have invented certain new and useful Improvements in Tobacco-Molds, of which the followingis a full, clear, and eX- x act description.`

My invention consists of a contrivance for arranging several series of tobacco-molds and followersin tiers by means of frames, by which the several series may be readily lifted apart after the pressing, to facilitate the removal of the pressed plugs and the filling of the cellsto be pressed again without the labor of lifting off the tier-frames and molds. 4

The invention also consists of improve ments in the construction of the molds for enabling them to be adj usted readily for making plugs of different sizes, all as hereinafter fully described.

AReference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the iiglires.

Figure l is a side elevation of my improved tobnocoanolds and pressing-frames, the frames being lifted apart for enabling the molds to be lled. Fig. 2 is an end elevation of the molds and frames as represented in Fig. 1, with some of the mold-boxes partly drawn ont and sectioned. Fig 3 is a plan view of one oi' the tier-frames and mold-boxes, showing didereut i'orms of the mold-cells. Fig. 4 is a plan view of one of the tier-frames inverted, showing the followers for pressing the tobacco in the cells. Fig. 5 is a section of two of vthe tier-frames on the line :c fo of Fig. 3. Fig. 6 is a perspective view of one of the tier-frames with the cross-bar of one end removed, and showing the manner of applying the followers. Fig. 7 isa perspective View of a mold-box with oneI oi' the partitions and the bottom detached.

I make a frame for each tier of 1nold-boxes, consisting of side plates or bars, a., connected rigidly at the center by a cross-piece, i), and removable end pieces, c, in which frame the press-follower d for the mold-boxes of the next tier below are carried by plates e, to which the followers are attached at the upper ends, and which slide into grooves f in the sides a when the end pieces, c, of the frames are removed. The plates e also enter similar grooves, j', in the cross-piece i); and the end pieces, c, also have grooves f, in which said plates enter when the end pieces are put on and secured to the ends of the side pieces, c. The moldbottoms g are then pnt on the plates e to be supported by them, and the mold-frames 71, are then put on the mold-bottoms to be supported by plates g and e. The frames thus construct ed are placed one on another, with dowel-pins for guides in any preferred number, according to the requirednumber of tiers of molds, and are connected by two pairs of lazy-tongs extensible frames is to each side, with which a lever, Z, is suitably connected for raising the frames apart and holdingv them by a rack, fm, as represented in Figs. i and 2, to enable the mold-boxes to be taken out for emptying and refilling ywithout the labor of lift-ing the tierframes apart, as at present arranged. Vhen the tieri'rames are thus raised up, the'followers d are raised out of the mold-cells, so that the boxes h can be wholly or partly drawn out for emptying and iilling after the end pieces, c, of the frames are removed, and when .the cells ofthe mold are refilled, preparatory to pressing again, the boxes may be easily and quickly shoved back and the end pieces, c, replaced, after which the frames are to be let down by the extensible toggle-frames, so that the followers rest on the tobacco in the moldcells, to be forced down in a press wherein the apparatus is to be supposed as resting while being filled and emptied, and by which the frames are to be pressed till the followers d descend in the mold-cells and press the tobacco into plugs,

The mold-boxes h are partitioned into cells, as required for the form and size of. the tobecco-plugs to be made, by partitions n o, which are notched at p for tting them together crosswise when the cells are to be so divided, and the box-sides have notches g for the end projections, s, of the partition o, said partition being-located at the middle of the boxes when short plugs are to be made;but the box sides and partitions nhave notches p and 'g' at one end, where said partition may be placed when longer plugs are to be made.

The bottoms g of the mold-boxes have IOO grooves t and rabbets u,in which the box sides and partitions extend below the upper surface ofthe bottom, to prevent the tobacco from being forced under them, and said bottom gis divided under the partition o, in the space of which the lower edge of the partition o ts when placed on the middle of the mold-box h, with a iilling-piece, o, below, which lli-ng piece is to be removed to enable the bottoni to be shoved together to close the space at the middle when.the partition o is placed at the back of the box for long plugs. The ,rabbet u is wider at the bacl; edge of the bottom, to extend under the mold-box side and withdraw from the same, to accommodate the shifting of the partitions. Vhen the mold-cells are thus extended, one of the followers is shifted close to the other by shifting one of the supporting-plates ein the grooves f and properly changing a filling-piece, fw; or different follow ers with different supporting-plates may be substituted.

The end pieces,'c,of the frames have holes through which tenons y of the side pieces,a,of the frames are passed to connect the end pieces, and they are secured by keys z. The'lower frame of the series is arranged on a bed, a,.

on which the apparatus is to be supported, and to Which-the levers Z, for working the extensible toggle-irames k, are pivoted at b for a iulcrum. The two extensible frames k of each side of the apparatus are connected together by a bar, c', to be Worked together and by one and the same lever, Z, which is connected to said bar.

On the upper edges of the sides a of the mold-frames I have provided overhanging strips b, to prevent the mold-boxes from rising up with the followers d when they withdraw from the molds, and the screws c,by whichv yhaving`mold-boxes and press-followers ar.

ranged therein, and said tier-frames connected by extensible frames for lifting them apart, substantially as described.

2. The tier-frames consisting of sides a, permanently connected by the center cross-piece, b, and the removable endfpieces, c, said sides,

eross-piece, and end pieces having grooves f for the follower-plates, substantially as described.

8. The combination, in tobacco-pressing apparatus, of the tier-frames having removable 'end pieces and grooved sides, ends, and crosspiece, press-followers attached to supportingplates fitted in said grooves, and mold-boxes supported on said follower-supports, substantially as described.

4. rlhe mold-boxes constructed with divided and adjustable. bottom g and adjustable partition o, and having a iilling-piece, fv, substantiallyas described.

5. The follower d, having separate supporting-plates e and fillers w, in combination with mold-boxes having adjustable partition o, substantially as described.
